When you're lookin for grains look first at the base malts, they're the malted grains that have active enzymes for saccrification. Most of the grains with all the flavors are crystal malts and the enzymes have been denatured. You can add small amounts of the crystal malts to add flavor but keep in mind that they have no active enzymes.
"Necessity is the plea for every infringement of human freedom. It is the argument of tyrants; it is the creed of slaves." William Pitt
